NAME
     rcsdiff - compare RCS revisions

SYNOPSIS
     rcsdiff [ -k_s_u_b_s_t ] [ -q ] [ -r_r_e_v_1 [ -r_r_e_v_2 ] ] [ -V_n  ]  [
     -x_s_u_f_f_i_x_e_s ] [ _d_i_f_f _o_p_t_i_o_n_s ] _f_i_l_e ...

DESCRIPTION
     rcsdiff runs diff(1) to compare two revisions  of  each  RCS
     file given.

     Pathnames matching an RCS suffix denote RCS files; all  oth-
     ers  denote working files.  Names are paired as explained in
     ci(1).

     The option -q suppresses diagnostic output.  Zero,  one,  or
     two  revisions may be specified with -r.  The option -k_s_u_b_s_t
     affects keyword substitution when extracting  revisions,  as
     described  in  co(1);  for  example, -kk -r1.1 -r1.2 ignores
     differences in keyword values when comparing  revisions  1.1
     and  1.2.  To avoid excess output from locker name substitu-
     tion, -kkvl is assumed if (1) at most one revision option is
     given,  (2)  no  -k option is given, (3) -kkv is the default
     keyword substitution, and (4) the working file's mode  would
     be  produced  by  co -l.  See co(1) for details about -V and
     -x.  Otherwise, all options of diff(1) that apply to regular
     files are accepted, with the same meaning as for diff.

     If both _r_e_v_1 and _r_e_v_2  are  omitted,  rcsdiff  compares  the
     latest revision on the default branch (by default the trunk)
     with the contents of the corresponding working  file.   This
     is  useful  for  determining what you changed since the last
     checkin.

     If _r_e_v_1 is given, but  _r_e_v_2  is  omitted,  rcsdiff  compares
     revision  _r_e_v_1  of  the  RCS  file  with the contents of the
     corresponding working file.

     If both _r_e_v_1 and _r_e_v_2 are given, rcsdiff compares  revisions
     _r_e_v_1 and _r_e_v_2 of the RCS file.

     Both _r_e_v_1 and _r_e_v_2 may be given numerically or symbolically.

EXAMPLE
     The command

             rcsdiff  f.c

     compares the latest revision on the default  branch  of  the
     RCS file to the contents of the working file f.c.
